Security audit

QMD CLI

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent local Markdown search helper, but its setup asks users to globally install a mutable third-party GitHub dependency without pinning or integrity checks.

Install only if you trust the qmd upstream source, and prefer a pinned commit or isolated environment. Add only the Markdown directories you intend to search because qmd can index and return full local document contents.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
